Augmentation of self-motion perception with synthetic auditory cues.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study tested whether a synthetic auditory cue, designed to encode translational self-motion, can augment vestibular perception. Twenty adults sat on a motion platform and judged whether forward translations were to the left or right of straight ahead (heading discrimination). Stimuli comprised vestibular-only, auditory-only, or combined vestibular-auditory cues. The auditory cue, presented via headphones, comprised a series of beeps, with motion speed encoded by beep rate, and heading direction encoded by simulating the sound to emanate from that direction. Combined-cue performance was better in comparison to vestibular-only. However, cue integration did not follow Bayesian predictions: the vestibular cue was overweighted. Moreover, combined-cue thresholds were better predicted by the empirically observed-rather than Bayesian-predicted-cue weights. Thus, humans can integrate synthetic auditory cues with natural vestibular cues to improve self-motion perception. However, they underweight the synthetic auditory cues. This suggests that cue weighting is determined not only by reliability, but also by inferred relevance.
